Extra Info:
blood-gradient hand vacuum

Blood sieved of chunky pieces sloshes around a cannister of tetraxenonoglass. Vacuum pressure sucks air in through the barrel, and slits on the slide stop vent a metronomic belch.

Weapon Class: Pistol
Accuracy: Medium

Compute power on the local lattice decreases the time needed for this item to generate ammunition.


A blood-gradient hand vacuum is a mid-to-high tier pistol, having a significant penetration value of 10. Although it does not have quite as high of a PV as some of the top-tier pistols, like the eigenpistol, hand rail, or spaser pistol, the hand vacuum has self replenishing ammo and can heal the wielder.

The blood-gradient hand vacuum has a blood reservoir and it can store up to 13 biologically-generated ammo units.

"an example image of the blood gradient hand vacuum in the inventory, showing that it is currently holding 7 drams of blood and has 4 shots, denoted in square brackets."

The blood reservoir is used primarily to generate "ammo" for the blood-gradient hand vacuum, but it also draws a small amount of energy from its blood reservoir whenever it fires a shot.

When the pulse hits a living creature, the wielder will heal 80-100% of the damage done, subtracted by 1-2 points. A maximum of ♥1d20+2021-40 (Avg: 30.5) per projectile can be healed with this method. This healing effect is reality distorting, so it will not work while astrally burdened or tethered.[1]

Technical Components

blood-gradient hand vacuum has the following technical components, each of which have special effects. The operational status of these components can be seen if the looker has access to a techscanning apparatus. Each of the components must be "Operational" to function.

  • ExsanguinationMicrotubules: This component extracts blood from the body of the equipper. Every 800 turns, it will refill a single dram of blood into the blood-gradient hand vacuum. Functionally, this acts as a slow but infinite recharge mechanism while the blood-gradient hand vacuum is equipped.[2]
    • This component will be operational only if equipped in a biological body slot. This typically means it must be equipped in one of a humanoid's default missile weapon equipment slots. It will not function while in the inventory or if equipped in a non-organic missile weapon equipment slot, such as the additional missile weapon slots granted by a gun rack implant.
  • VitalityTransferSystem: This component generates ammo for the blood-gradient hand vacuum. Every five turns (or less, with compute power), if blood is available in the reservoir, this component will fabricate 1 biologically-generated unit of ammo. The weapon can hold up to 13 units of ammo at a time. Each time that this component generates a unit of ammo, there is a 20% chance that it will consume 1 dram of blood from the weapon's reservoir.[3]
    • This component will be operational as long as at least one dram of blood is available in the weapon's reservoir. It works whether or not the blood-gradient hand vacuum is equipped; it will also generate ammo in the inventory.
  • EnergyWeaponSystem: This component fires the weapon. It consumes 100 charge each time it is fired. The charge is drawn from blood in the reservoir; but this tends not to have a significant noticeable effect on the blood available in the reservoir, because a single dram of blood can provide 7500 charge (enough to fire the weapon 75 times).[4]
    • This component will be operational as long as at least one dram of blood is available in the weapon's reservoir.
  • BiodynamicExtractor: This component is the power plant that converts blood into energy that the EnergyWeaponSystem can consume.[5]
    • This component remains operational at all times, but it requires at least one dram of blood to generate energy.

Advantages and Disadvantages

This section is opinion-based. Your mileage may vary.


  • Has an infinitely recharging ammo supply, and uses a liquid that is relatively easy to find.


  • If you use this as your only weapon, it can be difficult to keep it full at all times. It requires a significant blood supply, or else it requires time without firing to recharge.
